Can not access Discourse - blank page

[Dominika]

Hi to all,

we started having issues with our Discourse throughout the course of last week and can only see a blank page when we access it on our Wordpress site, the Discourse is not displaying.

I wondered if anyone has been experiencing the same and what the cause might be?

Kindly,

Have you tried using safe mode?

Use Safe Mode to troubleshoot issues with themes and plugins

Discourse has a “JavaScript Safe Mode”, where any user can use to isolate the root cause of a JavaScript issue caused by plugins, themes or theme components. To access safe mode go to: http://your-site-name/safe-mode for example this is the safe mode for our demo site: https://try.discourse.org/safe-mode [safe mode options] [safe mode is enabled] To exit safe mode simply close your browser tab When entering safe mode you can select between: Disable all themes and theme-components …

I had a similar problem few days ago, the culprit turned out to be AdBlock

Hey Dominika, just to confirm, are you only seeing an issue on Wordpress pages with Discourse comments enabled? If that’s the case, please share your Wordpress hosting provider. It may be the same issue reported here.

Error msg libxml_disable_entity_loader

Hi, I created a staging site for making changes on the production site.

I have the same issue here on meta with latest uBlock Origin (1.34.0), where it shows a blank page only. Other Discourse sites which are not using any of CloudFront do not show the same problems.

Edit: I’ve now purged all caches on the uBlock filter lists, updated all the filter lists and the problem is gone. Seems like they had CloudFront in one of their filters and this caused too much problems with legit sites using this Amazon AWS service.

Thank you all for comments, questions and suggestions - as of the latest development, I get 502 Bad Getaway nginx error when trying to open our Discourse on Wordpress.

I am in fact seeking a junior web master who would be able to help out with general Wordpress (and WP Discourse plugin) maintenance as well as be on hand when anything troubleshoots. If anyone is able to recommend someone good, I will appreciate the help.

For me, the solution of blank page was removal of:

GitHub - gdpelican/babble: Discourse Shoutbox plugin

Check out the plugin, which can open the browser F12 and then hit Web to refresh for more error messages.
